API Latency Tracker & Reporter

Measure your service reliability. This workflow pings your API every 15 minutes. It records the response time (latency) and HTTP status code. Every 24 hours, it aggregates these metrics into a mean-latency report and appends it to a Google Sheet, helping you visualize uptime trends and SLA compliance.
